SLIDE-RAIL HOLDER.

Specification of Letters Patent.

To all whom, it may concern:

Be it known that I, CLEVIA J. LUTHER,

a citizen of the United States, residing at.

vide novel means for holding a pair of auxiliary rails in properposition with re-, spect to the rails of a main track, and the inventionaims, generally, to improve and to enhance the utility of devices ofthat type to which the invention appertains.

With the above and other objects in view,

which will appear as the description pro ceeds', the invention residesin the combination and arrangement of parts and in the details ofconstruction heremafter described and claimed, it being understood that,within the scope of what is claimed, changes in the precise embodimentof the invention shown can be made without departing from the spirit ofthe invention.

In the accompanying drawings Figure 1 shows in top plan, a deviceconstructed in accordanc'e with the invention; Fig. 2 is a cross sectiontaken approximately on the line 22 of Fig. 1; and Fig. 3 is an endelevation.

By way of explanation, it may be stated that the main track rails 1 in amine, quarry or the like, do not extend up to the breast 2, to the endthat there may exist, between the extremities of the rails 1 and thebreast 2, a space of sufficient size to permit the operator to workadvantageously. As the breast is cut away, it is necessary to advancethe mine or quarry car toward the breast and use is made of auxiliaryrails 3. The balls 4 of the rails 3, technically known as slide rails,are introduced between the balls 5 of the main rails 1 and the flanges 6thereof, as shown in the Figs. 1 and 2, the balls 4 of the auxiliaryrails 3 abutting against the webs 7 of the main rails 1.

Spikes 8 are driven into the last tie 9 of the main track and hold theballs 4 in position as above described. It is obvious that the rails 3may be slid backwardly and for- Patented Mar. 9, 1920.

wardly as occasion may demand, and the use of the construction abovedescribed is, well understood by those skilled in the art. Its utility,however, has been impaired by reasonof the fact that, hitherto, noadequate means has been provided for connect ing the outer ends of theauxiliary or slide rails 3, to hold the rails 3K to gage, to ad-. justthe rails for various gages, and to prevent the mine or quarry car fromrunning oil the rails 3 asthe car approaches the breast 2., Having theforegoing in mind,

a longitudinally adjustable connection between the outer ends of therails 3 is provlded, in putting the present invention into practice.This longitudinally extensible ex' tension includes a pair of rods 10oppositely threaded as shown at 11, at their inner ends.

to cooperate with a turnbuckle 12. 1 1 exist at the outer ends of therods 10, the eyes being contracted, as shown at 15, intermediate theirends to fashion. outer loops 16 and inner loops 17. The outer loops 16receive the balls 1 of the auxiliary rails 0, whereas the inner loops 17receive the flanges 18 of the auxiliary rails, all of Eyes which will beclear from Fig.3, the inner loops 17 being somewhat wider than the outerloops 16, so that the result above mentioned may be accomplished.

It will be clear that the device forming the subject matterof thisapplication forms a convenient connection between the outer ends of theauxiliary ra1ls3. and permits them to be held at gage, and "to be adjusted for different gages, since mine and quarry tracks are not alwaysconstructed to a standard gage, but are gaged as circuin stances demand.It is to be observed, noting Fig. 3 particularly, that the eyes 1 1 ofthe longitudinally adjustable connection serve as bumpers, preventingthe mine car" from passing off the extremities ofthe auxiliary rails 3.

Having thus described the invention, what is claimed is In a device forholding slide rails, a pair of light portable rods the diameter of whichapproximates the verticalthickness of the balls of the rails to be held,the rods being provided at their outer ends with eyes In testimony thatI claim the foregoing which are shaped both externally and inas my own,I have hereto afiixed my signaternally to approximate roughly the crossturevin the presence of two Witnesses. 10 section of the slide rails,the eyes being 7 'CLEVIA J.
